Using /s to define variables instead of =s

[CGarson]

I've seen some PHP scripts using the / to define variables. For example:

http://url.com/some_script.php/variable/value
instead of
http://url.com/some_script.php?variable=value

Can someone help me with this?

Thanks!

I guess that is on apache side. You gotta use mod_rewrite to do such trick...
